Title: Centrifugal fan
Inventor: TAMAGAWA TORU
IPC: F04D29/28
Filed: 2002-04-12
Abstract: <P>PROBLEM TO BE SOLVED: To realize a small-size high-performance centrifugal fan for cooling a portable electronics.  <P>SOLUTION: A cantilever type impeller used for a centrifugal fan motor, comprises a rotation axis supporting part and a wall surface for preventing air current in the axial direction at one end part in the rotation axial direction, and an opening part at the other end part in the rotation axial direction.
